Ok will do . Both read good at 5 ohms
I don't think so. Compare voltages at R11 and R12. If they are equal and opposite and about 15 volts, we have no argument with diodes 10 and 19Could D2-10 be our culprit ??
While they are out and reading about 5 ohms, get back on the circuit board and expect infinity ohms across c11 and c12. We need to find out why you got a zero there previously.Ok will do . Both read good at 5 ohms
Fumble fingers!Don't know what I did but now it reads 5 ohms not 0.00
Therefore, not a problem. You measured across those 2 resistors and got equal voltages. If you read carefully, I said to measure AT those resistors. That means "to ground". That would have gotten you the 15 volts I claimed would be there. Amiright?R-11 and R-12 Both at 56v
Ok ok ..... maybe I'm just teeny weeny fumble fingered lol
R18 = .042 R17 = .006 and yes 5 ohms nice and proper when both soldered in
That's the voltages on zeners d3 and d8. So they're off a bit. I don't think it matters today. Those are error sensing circuits. Hoping they shut down any important parts while the speaker melted.R11 = 17.5v+ R12 = 16.5v-
From the left: C13 is blocking any DC from getting to D10 and D19Could D2-10 be our culprit ??
Looks good. The op-amp is happy... or burned upPin 7 reads 0.o75v+ .
ok ill start stating neg or pos
D2-10 is not our problem right now. It can only conduct if the output voltage AT THAT NODE is greater than -15 volts, and it can't be because there is no power transistor installed.I don't get wat u mean
I'm calling fumble fingers.So why aren't our voltages matching ??
